Chain like Phyllosilicate is

Phyllosilicate, are a compound with a structure in which silicate tetrahedrons each consisting of a central silicon atom surrounded by four oxygen at the corners of a tetrahedron are arranged in form of sheets or chains.
A chain like phyllosilicate is Palygorskite-sepiolite. Both of them have similar fibrous or lath-like morphologies, but palygorskite exhibits more structural diversity.
